This invention relates to an improvement in the springing of power driven vehicles more particular those in which the half .axles carrying e vehicle wheels-are arran d so that they can swing.

e invention is principa y intended to obtain a simplicity of the springing of the half axles with the best swinging qualities" such as have hitherto not'been achieved.

For this purpose, principally, unguided helical springs attached to the sprung parts without oints are rovided whic are practically completely ree from friction and require no ubrication.

According to the invention the simplicity is achieved especially by the springs bearing directly against the frame so that the frame girders are not subjected to twisting stresses and thereby the hitherto necessary spring mseats which with helical springs especially are very extended, are avoided. The longitudinal girders are not subjected to-twisting st and consequently special strengthenarrangement of the springs which emp eyes all the available 5 ace and a connection of the differential housing with the frame which 7 takes up the horizontal shocks especially, so areprovided,

- A. constructional advantage of the invention is illustrated in the aceompapging drawing,'in which Fig. 1 is a plan ew, Fig. 2

an end elevation and Fig. 3 a side elevation 5 of an axle sprun accordm to the invention.

The cross mem rs 2 an 3 of the frame to which the diflerential housin 4 is secured,

for exam le with rubber bu ers inte osed, are attac ed to the lon 'tudinal er 1. The axle tube 5, is hin to the housin by the journals 6 and I, w e the axle shaft is driven through the Cardan joint 8. The traverse 9, serving helical springs 10 and 11 is secured, to the axle tube 5. The other ends of the springs bear directly against the longitudinal girder 1 in such a manner that the spring forces do not produce any on the frame. The springs are, for example, constructed without guides and secured to the .half faxiia is connected with the frame, a travas an'abutment for the frame or to the half axles without joints so that the windings can adapt themselves to the arc of swing and are prevented from risin from the abutments by lockingpieces 12. this way the springing is especially simple. Undercertain circumstances, however, specially guided helical springs may also be used.

What I claim is 1. In a power driven vehicle, a chassis frame consisting of lateral longitudinal girders and transverse girders, a differential housing which is secured to the transverse girders of the chassis frame, a half axle receiving the drive for a vehicle wheel, a joint by which the half axle is jointed to the diflerv ential housing in such a manner that it can swing in a vertical plane and a helical spring substantially ungulded having one end bearing against the axle and the other end directly against a longitudinal girder from below..

2. In a power driven vehicle, a chassis frame consisting of lateral longitudinal girders and transverse girders, a half axle. carryin a vehicle wheel, a joint by which the erse secured to the axle which on each side of the axle has a spring abutment and two helical springs each having one end bearing against one of the spring abutments andwith the other end directly against a longitudinal girder from below.-

3. In a power driven vehicle, a chassis frame consisting of lateral longitudinal girders and transverse girders, a differential ousing which is secured to the transverse girders of the chassis frame, a half axle receiving the drive for a vehicle wheel, a joint bywhich the'half axle is jointed to the dif-. ferential housing in such a manner that it can swing in a vertical plane, a traverse secured to the axle which on each side of the axle has a spring abutment curved down under the axle, and two substantially unguided helical springs each having one end rigidly connect ed to one of the spring abutments and the other end directly with a longitudinal girder.

In testimony whereof I'aflix my signature.
